I plugged into ethernet (as wifi w/captive portal does not work for me). I think clearnet worked but I have no interest in that. Egress Tor traffic was blocked and so was VPN. I’m not interested in editing all my scripts and configs to use clearnet, so the library’s internet is useless to me (unless I bother to try a tor bridge).
I was packing my laptop and a librarian spotted me unplugging my ethernet cable and approached me with big wide open eyes and pannicked angry voice (as if to be addressing a child that did something naughty), and said “you can’t do that!”
I have a lot of reasons for favoring ethernet, like not carrying a mobile phone that can facilitate the SMS verify that the library’s captive portal imposes, not to mention I’m not eager to share my mobile number willy nilly. The reason I actually gave her was that that I run a free software based system and the wifi drivers or firmware are proprietary so my wifi card doesn’t work¹. She was also worried that I was stealing an ethernet cable and I had to explain that I carry an ethernet cable with me, which she struggled to believe for a moment. When I said it didn’t work, she was like “good, I’m not surprised”, or something like that.
¹ In reality, I have whatever proprietary garbage my wifi NIC needs, but have a principled objection to a service financed by public money forcing people to install and execute proprietary non-free software on their own hardware. But there’s little hope for getting through to a librarian in the situation at hand, whereby I might as well have been caught disassembling their PCs.
- Most folks will probably freak out when they see a terminal window ("DOS box") on a computer.
- Most folks in my country have no idea that there is something else than WhatsApp as alternative to SMS.
- Whenever I've tried explaining to people that stuff on their website violates privacy or when I try to explain why they are having email delivery problems almost always results in permanent silence or disbelief.
Technology appears to be a scare factor for a lot of people. But in this case the librarian maybe thought that Ethernet was only for their qualified IT department to use.
If it was a publicly available Ethernet port, it was likely for public use. The fact that she thought it was malicious speaks to ignorance on her part, not yours.
10+ years ago you had to bring your own ethernet cable to the University library because the WiFi couldn't handle all the students at peak times. Wo der if it's still the case.

You are on spot there, but sadly even legislators are far from understanding the reasons why this matters so much, let alone the general public.
Whatever security policy they have, it shouldn't require you installing a random executable to your system. And it was flawed enough that it didn't care to give your device access.
And by the way, it's so awesome you carry an ethernet cable around!!
This sounds odd to me, unless you connected to an Ethernet port behind a desk or somehow forced open a network closet… They also might not like it if you disconnected one of the public computers to use its cable/port; otherwise if this was an open and public port, you used it as designed and the librarian probably has watched too many Hollywood hacking movies. I have to admit, I never thought of this as a way to bypass the captive portal (sorta just assumed everyone going through the public network would have to hit it, kinda of the equivalent to having everyone sign a liability waiver).
With that said, I can see some institutions not liking connections that aren’t part of the more traditional/commercial networking (but it doesn’t sound like the library took issue with your traffic, just the librarian didn’t like the PHY link you chose to use). For the SMS thing (I haven’t seen that used in a while, you might be able to use some sort of burner number app if they don’t filter them).
